枚举 OffsetCommitMode

java.lang.Object

java.lang.Enum<OffsetCommitMode>

org.apache.flink.streaming.connectors.kafka.config.OffsetCommitMode

所有已实现的接口:

Serializable, Comparable<OffsetCommitMode>

@Internal
public enum OffsetCommitMode
extends Enum<OffsetCommitMode>

The offset commit mode represents the behaviour of how offsets are externally committed back to Kafka brokers / Zookeeper.

The exact value of this is determined at runtime in the consumer subtasks.

枚举常量概要

枚举常量

枚举常量和说明
DISABLED Completely disable offset committing.
KAFKA_PERIODIC Commit offsets periodically back to Kafka, using the auto commit functionality of internal Kafka clients.
ON_CHECKPOINTS Commit offsets back to Kafka only when checkpoints are completed.

方法概要

限定符和类型	方法和说明
static OffsetCommitMode	valueOf(String name) 返回带有指定名称的该类型的枚举常量。
static OffsetCommitMode[]	values() 按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。

枚举常量详细资料

DISABLED

public static final OffsetCommitMode DISABLED

Completely disable offset committing.

ON_CHECKPOINTS

public static final OffsetCommitMode ON_CHECKPOINTS

Commit offsets back to Kafka only when checkpoints are completed.

KAFKA_PERIODIC

public static final OffsetCommitMode KAFKA_PERIODIC

Commit offsets periodically back to Kafka, using the auto commit functionality of internal Kafka clients.

方法详细资料

values

public static OffsetCommitMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (OffsetCommitMode c : OffsetCommitMode.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static OffsetCommitMode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
